MAHLE Uses m+p Vibration Controllers for Automotive Parts Testing
MAHLE is one of the largest automotive suppliers worldwide for engine systems, filtration, engine peripherals, and thermal management. They successfully use vibration controllers from m+p international at sites in Germany, Austria and Brazil.
At its research and development site in Stuttgart/Germany, MAHLE Filtersysteme GmbH selected m+p VibControl software and m+p VibRunner measurement hardware for their vibration test rigs. Three test rigs are equipped with a slip table and temperature chamber which enables environmental simulation tasks combining vibration excitation with temperature control.
The wide variety of different specimens and vibration test equipment makes very high demands on the control of the test rigs. The vibration controllers need to combine very precise control, easy programmability and flexible parameter settings for the different specimen-dependent shakers.
MAHLE mainly uses classical test modes to simulate the excitations of engine and body: sine (swept sine, fixed-frequency sine, resonance dwell, multi-sine), broadband random, shock, sine-on-random. Over-testing is reliably avoided thanks to the notching function.
The daily test routine is greatly simplified by true multi-tasking functionality of m+p international’s vibration control system. The user is able to set up or edit a test, run a test, and analyse the acquired data, all at the same time.
